Oct.23 (GMM) Narain Karthikeyan has played down reports he is eyeing a switch to Indycar racing for 2013.

While Pedro de la Rosa is expected to remain at HRT next season, the Spanish team is believed to be assessing its options regarding the sister cockpit.

35-year-old Karthikeyan, however, insists he deserves to stay in 2013.

"I think I have been driving well and out-qualifying a senior pro like Pedro de la Rosa on a couple of occasions has given me immense confidence," he told the IANS news agency ahead of his home grand prix in India this weekend.

"I am fit and good enough to be in F1 for another two/three seasons."

The Indian, who was establishing a Nascar career in 2010 until he returned to F1 with HRT, denied he is now looking at returning to the American scene by seeking an Indycar test.

"I don't know where these rumours of me switching to Indycar emanated from," said Karthikeyan. "The brightest thing for 2013 will be another season with HRT."
